a representation of the probable years of survivorship of a defined population of subjects; given that survivorship is changed by new methods of prevention or treatment, a diachronic study is commonly used, the main interest of which lies in the composite structure of the current population. (In the summarizing technique used to describe the pattern of mortality and survival in a population, survivors to age x are denoted by the symbol lx and the expectation of life at age x is denoted by the symbol x.)

life tablePublic health A table that presents the results of a clinical study in which subjects enter and leave the trial at different times; each subject has a well-defined point of entry–onset of treatment and end point–relapse, death or other; all subjects may be evaluated at determined intervals with respect to the expected survival of an idealized person, based on actuarial analysis of census data and mortality rates
